TWI NE AND THE METHOD OF MAKING THE SAME.

SPECIFICATION -forming part of Letters Patent N 0. 437,386, dated September 30, 1890. I Application filed September I, 1889. Serial No..822,975. (Specimens) To aZZ whom it may concern.-

Be it known that I, FARMER R. WILLIAMS, a citizen of the United States, residing at Beloit, in the county of Rock and State of \Visconsin, have invented certain new and useful Improvements in Twine and the Method of Making the Same, of which the following is a full, clear, and exact specification.

The object of the invention is to produce a strong,'uniform, and pliable paper twine suitable for use in the binding of grain.

To this end my invention consists, first, in the method of manufacture, consisting in corrugating or crimping a strip or ribbon of paper longitudinally, so that it presents a zigzag form in-cross-section, thereafter gathering orcompressing this corrugated strip edgewise, and thus reducing its width, so that it becomes in effect a tape or ribbon of several thicknesses, and, finally, twisting this gathered strip.

My invention also consists in the twine the product of the above operation.

In the accompanying drawings, Figure 1 represents a strip of paper having one end creased or corrugated in the manner practiced in carrying outmy invention. Fig. 2 is a perspective View showing the manner of forming the creased or corrugated strip into twine.

In carrying my invention into effect I provide a strip of paper A, which may bemade from any stock possessing suitable strength and pliability and of any appropriate width, ordinarily of a width of about one inch. I crimp or corrugate this paper longitudinally -in parallel lines at uniform distances apart,

so that the surface is broken into a series of parallel flutes or corrugations, as shown at the right hand in Fig. 1, or, in other words, so that it presents a zigzag form in cross-section. After thus corrugating the sheet I gather it edgewise into a compact tape-like body, as shown at B, after which I twist it tightly into a close and solid twine, as shown at C.

The advantage of my method lies in the fact that after being crimped and closed together the strip may be twisted into a cord which is uniform in size and structure throughout its length, and in which the strains will be received lengthwise of the strip, so that the tensile strength of the paper is rendered fully available.

In the manufacture of paper twine the one 3 5 thing to be particularly guarded against is the twisting, crink1ing,or buckling of the paper in such manner that the strains will be received transversely, or that the strain shall be concentrated in one edge of the strip at any point in its length. 'By my method of procedure I am enabled to avoid these dangers.

I am aware that it has been proposed to gather a dampened strip of paper edgewise, and then twist it into twine, the means employed being such, however, that there were no definite, distinct, or uniform corrugations produced, it being entirelya matter of chance as to the manner in which the paper would break, crimp, or buckle during the gathering operation.

The distinguishing feature of myinvention is the crimping or corrugating of the paper in a definite and uniform manner and the closing of the same together previous to the twisting operation, so that in cross-section it presents several thicknesses or layers lying flatwise one upon another.

What I claim is- 1. A twine consisting of a strip longitudinally and uniformly corrugated, contracted edgewise, and twisted, all as described.

2. The method of manufacturing twine, consisting in first providing a paper strip with a series of uniform longitudinal corrugations, thereafter gathering the corrugated strip edgewise, so that it presents several layers or thicknesses, and finally twisting the same into twine.
